Im getting the wrong answer for when i try to solve for a trig inverse on the ti nspire cx


When you are dealing with trigonometric functions and their inverses, the results depend on the angle unit (degree, Radian, Gradian).
To set the correct angle unit (the one required by your problem)
  1. Turn calculator ON
  2. Press Menu key.
  3. Press 5:Settings>2:Settings>1:General
  4. On the second line Angle, there is a drop-down menu you activate by pressing the Right Arrow.
  5. Select Degree, Radian or Gradian and press Enter.
  6. Using the down Arrow move focus to the bottom of the screen where you can Make Default, or OK.
  7. Press one or the other.
  8. Validate your selection if asked.

My calculater has everything on the screen but its really light. I put in new batteries and it still doesnt work. Its a ti-84.


Turn the calculator on. Press and release the 2ND button. Press and hold the up-arrow button to increase the screen contrast. If you go too far, use the 2ND and down-arrow buttons to decrease the contrast.

Westinghouse - 60" Class / 1080p / 120Hz / LCD


There is a method called a Power Scan this method allows you to search for all possible codes. Try this until you reach a code that carries all of the functions desired. If the TV mode button starts flashing rapidly during this process you have exhausted all possible codes.
Power Scan
1.) Hold down the clear "TV" button on the remote for four seconds, then press 500 pound ( #)
2.) Hold down the clear "TV" button on the remote for four seconds, press the big power button once.
3.) Press the channel up button once per second until the TV turns off then press pound (#).

Inverse Functions on Casio fx-270W PLUS don't seem to work


because cotangent, cosecant, and secant are all inverse trig functions, just type in 1 / |shift| trig function and the number if you are finding the angles. It might not be a dedicated button, but its an extra push, and it will give you the same result. *note that I put the shift press only because that is how you get the inverse tan to get an angle from a tan ratio.*

Ti-83 plus


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

Reconnecting


When you turned off the Wii, did the light turn red or amber?
If you haven't done this already, hold the power button until it shuts off, and the light is red. Power it back up and try your remote again.
